Wide Angle X-ray Scattering (WAXS) is a technique used for the investigation of partially ordered materials. It is often employed to characterise the crystalline structure of polymers, by measuring the interatomic spacings within the unit cell. It is sub-nanometre-sized structures within the sample that cause the wide angles.
WAXS, essentially analogous to powder diffraction, provides information about crystallisation and can be measured simultaneously with SAXS.
